GANG-PLOW.

and facility.

My invention consists in the following construction and arrangement of parts whereby the object of my invention is attained, and which will be first fully described, and points of novelty set forth in the claim. All this will be fully seen in the course of the following description and by reference to the accompanying drawings, in which Figure 1 is aside elevation of my gang-plow. Fig. 2 is a top view. Figs. 3, 4, 5, and 6 are views in detail. Fig. 7 is a side view of my draft-pole or draw-beam.

The driving-wheels A of my gang-plow are mounted upon a wide transverse beam, consisting of the flatiron plate B,through the medium of the crank-axles O. The inner ends of these crank-axles have their bearing in studs or posts D, clipped or bolted to the ends of the plate, and intermediate between these posts or studs is placed the circular rack plates or disks E, with perforations E, the disk-plates being also rigidly connected to the cross beam or plate B.

To the crank-axles, intermediate between the inner studs or bearings and perforated diskplates,is rigidly connected by a key orset-screw the casings F, which carry the spring-arm le-,

vers F the latter'being provided with pins, which enter the holes in the disk-plates, and when these levers are operated they cause the cranks to assume a vertical or horizontal position, and carry with them the driving-Wheels to the right or left of the ends of the cross-beams, and consequently elevate or depress the plowframe and raise or lower the points of the plows, causingthem to cut a deeper or shallower furrow. The pins F upon the spring-levers, entering the holes in the disk-plates, keep the driving-wheels in the desired position upon their respective axles.

The plow-carrying portion of my frame con- (No model.)

sists of two flat-iron bars,G G, set edgewise, the outer ends of which are curved and scarfed to receive and hold the plows, the scarfed ends being bolted to the landside of the plows. The bar G of the frame extends backward a greater distance than its counterpart G, to provide space for the rear plow, and an angular brace, H, strengthens and supports the rear end of the frame, holding and keeping the two bars in a true vertical position edgewise. The frame is connected to the flat iron cross-beam by means of two stirrnps, I I, and a bolt-connection with the bar G passes through the beam B and stirrup I and pivots the frame at thatpoint to the cross-beam B, by means of which the whole running-gear of the plow is changed from a direct or straight line to the right or left ob-.

lique line or course in the following manner and by the means hereinafter described.

To the rear end of the bar G,I connect a perforated disk-plate, E having a spring-lever arm, E, identical with the devices heretofore described and lettered Ein the drawings. This plate is bolted to the bar G of the frame by the same bolt that connects the end of the brace H. The spring-lever arm is pivoted to the diskplate, and from the lower end extends an arm, J, also pivoted to the split end of ahorizontal connecting-rod, K, which connects with and is pivoted in turn to the beam B,so that when the pivoted lever of this disk-plateis moved backward or forward the end of the beam or plate B is moved with it by means of the jointed and pivoted connecting-rod, and permits the plow or machine to deviate from a right line to a right or left oblique. The stirrup I, being a greater length than its counterpart I, permits the driving-wheel at that end of the beam or plate to describe a greater curve than the wheel holes to receive a pin, which passes through the'end of the pole. That portion of the pole represented at P is composed of wood, the inner end of which is received between the stirrnps or arms P of the metal beam or portion P in which position the two parts are connected by the transverse bolts P. A strengthening-strap, Q, is bolted to the upper face of the pole. A strap, (1*, is secured to its under side, and a bolt, Q passes through the strap or clip and pole, to which the evcner or double-tree and whiilletrecs are pivoted in such a manner that the pull will be more nearly on the center or horizontal line of draft, and not have a tendency to drag the points ofthe plows downward. This, together with the inner end of the pole, elevates or depresses the machine to correspond with the position and the line of draft, the plou points, and the driving-wheels.

Having thus described my invention, what I ERNEST 1*]. KRA'USE.
